SPECIFICATION forming part of Letters Patent No. 771,534, dated October4, 1904. Application filed November 20, 1903. Serial No. 181,894. (Nomodel.)

T at whom it may concern:

Be it known that I, WILLIAM P. CLIFFORD, a citizen of the United States,residing at 100-. nium, in the county of Appanoose and State of Iowa,have invented certain new and useful Improvements in Motors, of whichthe following is a specification.

My invention relates to improvements in motors designed with specialreference for use in grain-elevators and similar structures where asimple, efi'icient, and economical elevating power is desired. Theinvention may also be found useful in small factories and, in fact, inany place where it is desired to operate any 5 light machinery.

The invention is designed to be operated by means of the weight of theteam, wagon, and load passing over a spring-yielding driveway dividedinto sections adapted to generate power by means of mechanism to behereinafter described and storing up and utilizing the power thusgenerated by means of weights or springs or similar devices.

With these ends in view the invention consists in the novelconstruction, arrangement, and combination of parts hereinafterdescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure lis a view in elevation of my invention as applied to an ordinarygrain-elevator. Fig. 2 is a top plan view of the winding-drums withconnecting mechanism for running the elevator proper. Fig. 3 is a topplan view of the mechanism located beneath the driveway. Fig. 4 is arear plan view of the winding-drums, showing a more detailed viewof theconnecting mechanism for running the elevator proper and the means forreversing the drums and throwing the same into and out of gear with saidconnecting mechanism. Fig. 5 is adetail view of one of the ratchetsprocket-wheels of the winding-drums.

Similar numerals of reference indicate like parts throughout all thefigures of the draw- In the drawings, 1 designates the frame of anordinary elevator-building provided with 5 an elevator-box 2, containingthe usual ele-. vator-belt and buckets actuated by a driveshaft 3 andpulley 4, receiving power by means of a main driving-belt 5, passingover a second pulley attached to the mechanism to 55 be hereinafterdescribed.

6 designates the supporting-beams of the driveway 7, provided with aplatform divided into sections 8, suitably mounted on springs 9,supported on said supporting-beams 6 and designed to yieldingly hold andsupport the sections 8.

1O designates blocks provided with adjusting-bolts 11, designed to limitthe movements of the spring-mounted sections 8 and regu- 5 late the dipor distance said sections will be depressed while being actuated by theteam and load passing over the same.

Mounted in suitable journals attached to the overhead supporting-beams12 above each 7 section 8 is a set of shafts 13, provided withsprocket-wheels 1 4: and ratchet-wheels 15, actuated by means of pawls16, connected to the sections 8 by means of rods 17.

18 designates sprocket-chains passing over the sprocket wheels 14 andover sprocketwheels 19, secured to the ends of shafts 20, mounted insuitable bearings 21, secured to beams 22, mounted beneath the driveway7.

23 designates ratchet-wheels mounted on 30 the shafts 20, provided withpawls 24, which prevent the shafts from revolving in a reversedirection. Upon the ends of the shafts 20 are secured sprocket-wheels25.

26 designates sprocket-chains passing over 5 said sprocket-wheels 25 andover sprocketwheels 27, secured to shafts 28, carrying the winding-drums29, slidably mounted thereon. The shafts 28 are mounted in suitablebearings 29*, secured to the upright supporting- 9 beams 30. Thewinding-drums 29 are provided at one end with a sliding clutch 31,

adapted to be thrown into and out of engagement with the sprocket-wheels27, and upon their opposite ends are provided with sleeves or ferrules32, provided with ratchetswheels 33, (see Fig. 5,) adapted to be engagedby a series of pawls 34, pivotally arranged within sprocket-wheels 35.The shafts 28 are provided at their ends with ribs or flanges 36,adapted to take into recesses 37 on the interior of the sleeves orferrules 32, so as to permit the same, together with the attachedsprocket-wheels 35, winding-drums 29, and clutches 31, to be movedlaterally into and out of engagement with the sprocket-wheels 27 bymeans of operating-levers 38, pivotally mounted on supporting-arms 39,secured to one of the upright supporting-beams 30, the lower ends ofwhich operating-levers 38 take into an annular recess 40 of the sleevesor ferrules 32.

41 designates sprocket-chains passing over the sprocket-wheels 35 andover sprocket-. wheels 42, mounted on a shaft 43, secured to asupporting-beam 44 by means of a bearing 45. (See Fig. 2.) Carried byand mounted on said shaft 43 is a bevel gear-wheel 46, meshing with apinion 47, secured to the end of a line-shaft 48, mounted in suitablebearings attached to the frame of the elevatorbuilding. 49 designates amain driving-pulley mounted on said line-shaft 48, over which passes themain driving-belt 5, which passes over and revolves the pulley 4,mounted on shaft 3, which operates the elevator-belt in the elevator-box2.

5O designates wire ropes attached to and adapted to be wound upon th ewinding-drums 29, passing over pulleys 51, suitably mounted on asupporting-beam 52 in the lower por-.

tion of the elevator-building and up and over a second series of pulleys53, suitably mounted on one of the upper beams of the elevatorbuildingand having attached to their overhanging ends weight-boxes 54, adaptedto receive any proper form and suitable amount of weighting material. 55designates a second pulley mounted on the line-shaft 48 and carrying abelt 56, passing overa pulley 57, mounted on a shaft 58, secured tosupportingbeams 59 by means of bearings 60. 61 designates a secondpulley mounted on said shaft 58 and carrying a belt 62, passing over apulley 63, mounted on a shaft 64, secured to the supporting-beams 59 bymeans of bearings 63. Upon the end of said shaft 64 there is secured abevel-gear 65, meshing with a second bevel-gear 66, secured to the lowerend of a vertically-arranged revoluble sleeve 67, mounted on a verticalshaft 68 and having secured at its top ordinary governor arms and balls69.

7 O designates a bar pivotally mounted on a supporting-bar 71 and havingslidably mounted thereon balls 72, which are adapted to be adjusted toany desired point on the bar 7 0, whereby the speed of the governor andthe mechanism controlled thereby may be regulated.

72 designates a bar pivotally secured atits lower end to the bar and atits upper end to a spring 73, which acts as abrake on a pulley 7 4,secured to the shaft 58, around which the spring 73 extends.

The operation of the invention is as follows: The team, with wagon andload, enters and passes up driveway 7 and over the sections 8 of theplatform and in passing over the various sections in ascending theplatform depresses the same with the connecting-rods 17 and pawls 16,which said pawls actuate the ratchetwheels 15, revolving the shafts 13,sprocketwheels 14, sprocket-chains 18,sprocket-wheels 19, shafts 20, andsprocket-wheels 25. By means of the sprocketchains 26 passing over thesprocketwheels 25 and over the sprocket-wheels 27 motion is transmittedto the winding-drums 29, causing them to revolve and wind up the ropes50 with the attached weights 54. In this way the operation of winding upthe ropes 50 with weights 54 is continued while the team, with Wagon andload, is passing over the various sections of the driveway until themainfloor of the elevator is reached. If desired, the exit driveway maybe similarly equipped with mechanism for still further storing up theenergy of team and wagon passing over driveway, if found necessary ordesirable. Furthermore, the driveway may be constructed of any desiredlength found necessary to secure the desired amount of power. After theload has been dumped the winding-cylinders 29 are thrown out ofconnection or gear with the sprocket-wheels 27 by means of theoperatinglevers 38, thus allowing the winding-drums by the pull of theweights 54 unwinding the ropes 50 and causing the sprocket-wheels 35 tobe revolved by reason of the pawls 34 coming into engagement with theratchet-wheels 33. As the sprocket-wheels 27 are being revolved thesprocket-wheels 42 are caused to be revolved by means of thesprocket-chains 41, passing over the same, and the revolution of theshaft 43, carrying the bevel gear-wheel 46, is caused to be revolved,together with the pinion 47 meshing therewith. The revolution of theline-shaft 48, to which said pinion 47 is attached, causes the pulleys49 and 55,

carried thereby, to be revolved, and these pulleys by means of the belts5 and 56 transmit motion to the elevator and governor, whereby the sameare operated, respectively.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principles orsacrificing any of the advantages of this invention.

29 to revolve in an opposite direction, caused Having thus explainedthe'nature of my invent-ion and described a way of constructing andusing the same, although without having attempted to set forth all theforms in which it may be made or all the modes of its use, I declarethat what I claim, and desire to secure by Letters Patent, is-
